An online detection device for rolling mill roll system stability

Abstract

A mill roll system stability online detecting device comprises a vertical sliding way with the lateral face fixed to the outer lateral face of a bearing pedestal, a sliding block in sliding connection with the vertical sliding way, a drawing pin bent to be in a right-angle shape and a drawing board with the bottom face fixed to the plane of a mill housing, wherein the vertical sliding way is in a barrel shape, the center line of the vertical sliding way is perpendicular to the plane of the mill housing, and the opposite side of the fixed side of the vertical sliding way is provided with a vertically through notch; an outer thread is arranged at the tail portion of the drawing pin and connected with a pre-load nut; the drawing pin is fixed to the notch of the vertical siding way through the pre-load nut; the sliding block is provided with a sliding block screw hole matched with the outer thread of the tail portion of the drawing pin; the tail portion of the drawing pin penetrates through the notch of the vertical sliding way and is in threaded connection with the sliding block screw hole; the drawing board is a rectangular board with scales on the center lines in the length and width directions. The mill roll system stability online detecting device can record the outwards shifting amount of a working roll and the cross amount of the working roll and the bearing pedestal in real time, so that the position of a roll system sliding board is adjusted accurately, the crossing of a roll system is effectively eliminated, good control over the middle board type is achieved while equipment faults are avoided, and the yield of steel boards is improved.

Description

technical field [0001] The invention relates to an online detection device for roll system stability of a rolling mill, which belongs to the technical field of metal rolling equipment. Background technique [0002] During the production process of medium plate rolling mills in metallurgical enterprises, the sliding plate of the window of the rolling mill is easy to wear, and the working condition of the window is bad, which has caused the problem of crossing of the upper and lower work rolls to become increasingly prominent. The phenomenon of roll jumping (working rolls jumping outward along the axis) seriously affects the operator's control of the plate shape, and further restricts the improvement of the yield of the steel plate; at the same time, the roll jumping phenomenon caused by the crossing of the roll system, Causes frequent equipment failures, which restricts the increase in the output of the medium plate line; when the roll system crosses seriously, the camber of ...

[0002] During the production process of the medium plate rolling mill in metallurgical enterprises, the sliding plate of the window of the rolling mill is easy to wear, and the working condition of the window is bad, which causes the problem of crossing of the upper and lower work rolls to become increasingly prominent. The phenomenon of roll jumping (working rolls jumping outward along the axis) seriously affects the operator's control of the shape of the plate, and further restricts the improvement of the yield of the steel plate; at the same time, the roll jumping phenomenon caused by the crossing of the roll system, Causes frequent equipment failures, which restricts the increase in the output of the medium plate line; when the roll system crosses seriously, the camber of the steel plate becomes heavier and cannot be eliminated through normal HAGC roll gap adjustment, and the plate shape cannot be controlled at all, so the roll system crossing situation is alleviated imminent
